Follow these rules below to ensure general safety:

• Observe a good housekeeping in the area where the machines are put duringand after the maintenance.

• When lifting any heavy object:1. Make sure that you can stand safely without slipping.2. Distribute the weight of the object equally between your feet.3. Use a slow lifting force. Never move suddenly or twist when you attempt

to lift it.4. Lift it by standing or pushing up with your leg muscles; this action could

avoid the strain from the muscles in your back. Do not attempt to lift anyobject that weighs more than 16 kg (35 lb) or that you think is too heavy foryou.

• Do not perform any action that causes hazards to the customer, or that makesthe machine unsafe.

• Before you start the machine, make sure that other service representativesand the customer are not in a hazardous position.

• Please remove covers and other parts in a safe place, away from allpersonnel, while you are servicing the machine.

• Keep your toolcase away from walk areas so that other people will not trip itover.

• Do not wear loose clothing that can be trapped in the moving parts of themachine. Make sure that your sleeves are fastened or rolled up above yourelbows. If your hair is long, fasten it.

• Insert the ends of your necktie or scarf inside clothing or fasten it with the

nonconductive clip, about 8 centimeters (3 inches) from the end.• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for

your clothing.Attention: Metal objects are good electrical conductors.

• Wear safety glasses when you are hammering, drilling, soldering, cuttingwire, attaching springs, using solvents, or working in any other conditionsthat may be hazardous to your eyes.

• After service, reinstall all safety shields, guards, labels, and ground wires.Replace any safety device that is worn or defective.

• Reinstall all covers correctly before returning the machine to the customer.• Fan louvers on the machine help to prevent the overheating of internal

components. Do not obstruct fan louvers or cover them with labels orstickers.

Observe the following rules when working on electrical equipments.

• Find the room emergency power-off (EPO) switch, disconnecting switch, orelectrical outlet. If an electrical accident occurs, you can then operate theswitch or unplug the power cord quickly.

• Do not work alone under hazardous conditions or near the equipment thathas hazardous voltages.• Disconnect all power before:

– Performing a mechanical inspection– Working near power supplies– Removing or installing main units

• Before you start to work on the machine, unplug the power cord. If youcannot unplug it, ask the customer to power-off the wall box that suppliespower to the machine, and to lock the wall box in the off position.

• If you need to work on a machine that has exposed electrical circuits, observethe following precautions:– Ensure that another person, familiar with the power-off controls, is near

you.Attention: Another person must be there to switch off the power, ifnecessary.

– Use only one hand when working with powered-on electrical equipment;keep the other hand in your pocket or behind your back.Attention: An electrical shock can occur only when there is a completecircuit. By observing the above rule, you may prevent a current frompassing through your body.

– When using testers, set the controls correctly and use the approved probeleads and accessories for that tester.

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate

you from grounds such as metal floor strips and machine frames.Observe the special safety precautions when you work with very high voltages;instructions for these precautions are in the safety sections of maintenanceinformation. Be extremely careful when you measure the high voltages.• Regularly inspect and maintain your electrical hand tools for safe operational

condition.• Do not use worn or broken tools and testers.• Never assume that power has been disconnected from a circuit. First, check it

to make sure that it has been powered off.

Electrical safety

Important:

Use only approved tools and test equipments. Some hand tools havehandles covered with a soft material that does not insulate you whenworking with live electrical currents.Many customers have rubber floor mats near their machines that containsmall conductive fibers to decrease electrostatic discharges. Do not use suchkind of mat to protect yourself from electrical shock.

• Always look carefully for possible hazards in your work area. Examples ofthese hazards are moist floors, nongrounded power extension cables, powersurges, and missing safety grounds.

• Do not touch live electrical circuits with the reflective surface of a plastic

dental mirror. The surface is conductive; such touching can cause personalinjury and machine damage.• Do not service the following parts with the power on when they are removed

from their normal operating places in a machine:– Power supply units– Pumps– Blowers and fans– Motor generatorsand similar units. (This practice ensures correct grounding of the units.)

• If an electrical accident occurs:– Use caution: do not become a victim yourself.

– Switch off the power.– Send the victim to get medical aid.

Any computer part containing transistors or integrated circuits (ICs) should be

considered sensitive to electrostatic discharge (ESD). ESD damage can occurwhen there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and theperson handling the part are all at the same charge.

When handling ESD-sensitive parts:• Keep the parts in protective packages until they are inserted into the product.• Avoid contact with other people.• Wear a grounded wrist strap against your skin to eliminate static on your

body.• Prevent the part from touching your clothing. Most clothing is insulative and

retains a charge even when you are wearing a wrist strap.• Use the black side of a grounded work mat to provide a static-free work

surface. The mat is especially useful when handling ESD-sensitive devices.• Select a grounding system, such as those listed below, to provide protection

that meets the specific service requirement.

– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

– When working on a double-insulated or battery-operated system, use anESD common ground or reference point. You can use coax or connector-outside shells on these systems.

– Use the round ground prong of the ac plug on ac-operated computers.

Electrical grounding of the computer is required for operator safety and correctsystem function. Proper grounding of the electrical outlet can be verified by acertified electrician.

Handling devices that are sensitive to electrostatic discharge

Notes:

1. Use product-specific ESD procedures when they exceed therequirements noted here.

2. Make sure that the ESD protective devices you use have been certified(ISO 9000) as fully effective.

Notes:

The use of a grounding system to guard against ESD damage is desirable butnot necessary.

Strategy for replacing FRUs




21/88

Important service information-

17

Use the following strategy to prevent unnecessary expense for replacing andservicing FRUs:• If you are instructed to replace an FRU, but the replacement does not solve

the problem, reinstall the original FRU before you continue.

• Some computers have both a processor board and a system board. If you areinstructed to replace either of them, and replacing one of them does not solvethe problem, reinstall that board, and then replace the other one.

• If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove theFRUs one by one to see if the symptoms change. Replace only the FRU thatchanged the symptoms.

Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Notethe current configuration settings (using the View Configuration option); then,when service has been completed, verify that those settings remain in effect.

Strategy for replacing a hard disk driveAlways try to run a low-level format before replacing a hard disk drive. This willcause all customer data on the hard disk to be lost. Make sure that the customerhas a current backup of the data before performing this action.

Attention: The drive startup sequence in the computer you are servicing mayhave been changed. Be extremely careful during write operations such ascopying, saving, or formatting. If you select an incorrect drive, data or programscan be overwritten.

Important notice for replacing a system boardSome components mounted on a system board are very sensitive. Improperhandling can cause damage to those components, and may cause a systemmalfunction.

Attention: When handling a system board:• Do not drop the system board or apply any excessive force to it.• Avoid rough handling of any kind.• Avoid bending the system board and hard pushing to prevent cracking at

each BGA (Ball Grid Array) chipset.

RoHS, The Restriction of Hazardous Substances in Electrical and

Electronic Equipment Directive (2002/95/EC) is a European Union legalrequirement affecting the global electronics industry. RoHS requirements

must be implemented on Lenovo products placed on the market after June

2006. Products on the market before June 2006 are not required to have

RoHS compliant parts. If the original FRU parts are non-compliant,

replacement parts can also be non-compliant. In all cases if the original

FRU parts are RoHS compliant, the replacement part must also be RoHS

compliant.

Note: RoHS and non-RoHS FRU part numbers with the same fit and function areidentified with unique FRU part numbers.

Lenovo plans to transit to RoHS compliance well before the implementation dateand expects its suppliers to be ready to support Lenovo’s requirements andschedule in the EU. Products sold in 2005 and 2006 will contain some RoHScompliant FRUs. The following statement pertains to these products and anyproduct Lenovo produces containing RoHS compliant FRUs.

RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHSimplementation date, failed RoHS compliant parts must always be replaced withRoHS compliant ones, so only the FRUs identified as compliant in the systemHMM or direct substitutions for those FRUs may be used.

Note: A direct substitution is a part with a different FRU part number that isautomatically shipped by the distribution center at the time of the order.

• Replace an FRU only with another FRU of the correct model. Whenyou replace an FRU, make sure that the machine model and the FRU partnumber are correct by referring to the FRU parts list.

• An FRU should not be replaced just because of a single,

unreproducible failure. Single failures can occur for a variety of reasonsthat have nothing to do with a hardware defect, such as cosmic radiation,electrostatic discharge, or software errors. Consider replacing an FRUonly when a problem recurs. If you suspect that an FRU is defective,

clear the error logs and run the test again. If the error does not recur, donot replace the FRU.• Be careful not to replace a nondefective FRU.

To verify a symptom, follow the steps below:

1. Turn off the computer.2. Remove the battery pack.3. Connect the AC adapter.4. Make sure that power is supplied when you turn on the computer.5. Turn off the computer.6. Disconnect the AC adapter and install the charged battery pack.7. Make sure that the battery pack supplies power when you turn on the

computer.

If you suspect a power problem, see the appropriate one of the following powersupply checkouts:

• see “Checking the AC adapter” on page 21• see “Checking operational charging” on page 21• see “Checking the battery pack” on page 22

Checking the AC adapterYou are here because the computer fails only when the AC adapter is used.• If the power-on indicator does not turn on, check the power cord of the AC

adapter for correct continuity and installation.• If the computer does not charge during operation, go to “Checking

operational charging”.

To check the AC adapter, follow the steps below:

1. Unplug the AC adapter cable from the computer.2. Measure the output voltage at the plug of the AC adapter cable. See thefollowing figure:

Note: Output voltage for the AC adapter pin No. 2 may differ from the one you

are servicing.3. If the voltage is not correct, replace the AC adapter.4. If the voltage is acceptable, do the following:• Replace the system board.• If the problem persists, go to see “Lenovo G700/G710” on page 27.

Note: Noise from the AC adapter does not always indicate a defect.

Checking operational chargingTo check whether the battery charges properly during operation, use adischarged battery pack or a battery pack that has less than 50% of the totalpower remaining when installed in the computer.

Perform operational charging. If the battery status indicator or icon does notlight on, remove the battery pack and let it return to room temperature. Reinstallthe battery pack. If the charge indicator or icon is still off, replace the batterypack.

If the charge indicator still does not light on, replace the system board. Thenreinstall the battery pack. If it is still not charged, go to the next section.

Checking the battery pack Battery charging does not start until the Power Meter shows that less than 95%of the total power remains; under this condition the battery pack can charge to100% of its capacity. This protects the battery pack from being overcharged orfrom having a shortened life.

To check your battery, move your cursor to the Power Meter icon in the icon tray

of the Windows® taskbar and wait for a moment (but do not click it), and thepercentage of battery power remaining is displayed. To get detailed informationabout the battery, double-click the Power Meter icon.

Note: If the battery pack becomes hot, it may not be able to be charged. Removeit from the computer and leave it at room temperature for a while. After it coolsdown, reinstall and recharge it.

To check the battery pack, follow the steps below:1. Turn off the computer.2. Remove the battery pack and measure the voltage between battery terminals

1 (+) and 7 (-). See the following figure:

3. If the voltage is less than +11.0 V DC, the battery pack has been discharged.

Note: Recharging will be continued for at least 3 hours, even though theindicator does not light on.

If the voltage is still less than +11.0 V DC after recharging, replace the battery.4. If the voltage is more than +11.0 V DC, measure the resistance between

battery terminals 5 and 7. The resistance must be 4 to 30 K.If the resistance is not correct, replace the battery pack. If the resistance iscorrect, replace the system board.

As many as three passwords may be needed for any Lenovo computer: the

power-on password (POP), the hard disk password (HDP), and the supervisorpassword (SVP).

If any of these passwords has been set, a prompt for it appears on the screenwhenever the computer is turned on. The computer does not start until thepassword is entered.

Exception: If only an SVP is installed, the password prompt does not appearwhen the operating system is booted.

Power-on passwordA power-on password (POP) protects the system from being powered on by anunauthorized person. The password must be entered before an operating system

can be booted.

Hard-disk passwordThere are two hard-disk passwords (HDPs):

+ User HDP - for the user

+ Master HDP - for the system administrator, who can use it to get access to thehard disk drive even if the user has changed the user HDP

Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be used for access to the hard disk drive. If no masterHDP is available, neither Lenovo nor Lenovo authorized service techniciansprovide any services to reset either the user or the master HDP, or to recover data

from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.

Supervisor passwordA supervisor password (SVP) protects the system information stored in the BIOSSetup Utility. The user must enter the SVP in order to get access to the BIOSSetup Utility and change the system configuration.

Attention: If the SVP has been forgotten and cannot be made available to theservicer, there is no service procedure to reset the password. The system boardmust be replaced for a scheduled fee.

Note: The remainder of the recovery process is fully automated and no

action is required by you. The computer will restart into the Windowsdesktop several times and you might experience periods when no activity isapparent on the screen for several minutes at a time. This is normal.
